Solve by using the addition method.. Provide the solution set:
3x^2-5y^2=-33
2x^2+5y^2=35

cwrw238 · Answer

when you add these 2 equations the terms in y disappear  to give
5x^2 = 2

solve for x (there will be 2 solutions)
and plug these into one of the original equations to find the values of y.

can you finish this or need more help?

anonymous · Answer

But now I have another one that the y values do not disappear?!

anonymous · Answer

And I dont get them!!

cwrw238 · Answer

ok post it

anonymous · Answer

2x^2-3y^2=-19
3x^2+2y^2-30

cwrw238 · Answer

ok
to do this you multiply equation 1 by 2 and equation 2 by 3 to give

4x^2 - 6y^2 = -38
9x^2 + 6y^2 = 90

is that = 30 in second equation?

anonymous · Answer

yes sorry
lol

cwrw238 · Answer

ok
so if you add these 2 equations you will eliminate y

cwrw238 · Answer

when you multiply equations be sure to multiply each term

good

cwrw238 · Answer

that is what this website is for.
